In which hemisphere are Broca's speech area and the auditory association area located for a right-handed individual?

Broca's area and the auditory association area are primarily located in the left cerebral hemisphere for a right-handed individual. This is due to the lateralization of language functions in the brain, where the left hemisphere is typically dominant for language processing. Broca's area, located in the frontal lobe, is crucial for speech production and language processing, while the auditory association area, which resides in the temporal lobe, is involved in the interpretation of auditory information, including language.

In right-handed individuals, approximately 95% have language functions localized to the left hemisphere. Therefore, both Broca's area and the auditory association area being in the left hemisphere underscores the specialization and structural organization of the brain regarding language and communication functions. This physiological setup is significant in the study of speech therapy, as it informs clinicians about the potential areas affected in individuals with language disorders.
